Amazon Software Development Engineer-II interview questions

Was very challenging and a lot of fun, mostly CS stuff :) Several roationions with other developers writing code on the white board. Time and space complexity questions.

I was contacted by a recruiter and after an initial screening, i was given an online test to complete. Once i submitted that, i was informed that i cleared the test and was invited over to Seattle for the onsite interview. The interview was a very positive experience. I had 5 interviews each 45-mins in Seattle. 4 of them included white board coding and 1 was purely behavioral. It was a very positive experience for me overall. However i did feel a bit bad about the way one of the interviewers behaved. i was writing on the whiteboard and i turned to explain, i saw the interviewer rolling her/his eyes at me. that was a real mood killer and my confidence did a nose-dive. I had heard that amazon trained their interviewers extensively and this particular behavior was surprising to say the least and left a bad taste. I was able to give solutions for every single problem in all these interview sessions and had thought i might get an offer. Unfortunately, i did not get through !
